Experimental observation of microwave induced resonances in magneto-optic trap

Results on study of MOT fluorescence in presence of microwave field applied to ground state splitting of atoms in trap are presented. Experiments are performed with rubidium atoms in conventional three circular polarized retroreflected beams magneto-optical trap setup in the next conditions. To make trapping, two external cavity diode lasers frequency locked to saturated absorption peaks at D-2 line of rubidium are used. The power of each laser is about 6 mW. The locking circuit allowed the tuning of offset frequency within wing of saturation absorption peak via computer.
